Router in bridge mode

I have a cisco 2621 router left in town A, settings as below. I have a cisco
2621 router
right in town B, settins as below. I cannot change the ip addresses or
interfaces.
To connect them I thought I could use a cisco 2621 router in bridge mode and
made a
config 'middle' as below. It doesn't work. What is a good solution for this
problem? Help.
